Micro Abstract:
In this contribution a mixed hybrid shell element for the calculation of interlaminar shear and normal thickness stresses of layered composite structures is presented. These stresses are decisive factors for delaminations. The element formulation is based on the Reisser-Mindlin kinematics with an inextensible director field. After static condensation the element has the standard shell degrees of freedom. The numerical examples focus on failure caused by delamination.
